overlay_map.dtb arranges that when config.txt requests "vc4-kms-v3d"
the rpi4 will actually load "vc4-kms-v3d-pi4" and fixups like that.
It is present on the official distros, and must be put into the
overlays subdirectory in the boot partition.
For a detailed description of the overlay_map.dts file see:
https://www.raspberrypi.org/documentation/configuration/device-tree.md#part2.2.10
vc4-kms-v3d-pi4 is required for the arm based kms driver on the rpi4.

In theory, this would allow one to use the official 7-inch touchscreen
in combination with the (non-firmware) kms driver by adding the
following lines to config.txt:
ignore_lcd=1
dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-7inch

It has prebuilt binary libgpiod_pulsein for rpi machines and these binary is 32bit
therefore we can not include it for 64bit machines even if they are rpi
based unless they have multilib enabled.
This patch makes it visible only on 32bit rpi
Fixes QA errors like
ERROR: QA Issue: Architecture did not match (ARM, expected AArch64) in /usr/lib/python3.9/site-packages/adafruit_blinka/microcontroller/bcm283x/pulseio/.debug/libgpiod_pulsein [arch]

introduced python3-adafruit-blinka and this recipe has added rdep on rpi-gpio,
however rpi-gpio is rpi specific package, and therefore should only be added
when building rpi based platforms, this makes the layer work in a
multi-bsp setup work

gstreamer1.0-omx receipe on OE-core sets:
core-name=${GSTREAMER_1_0_OMX_CORE_NAME} on the installed gstomx.conf
in this case it will set:

Currently, the do_compile log is cluttered with dtc warnings that should only
be printed when compiling with W="123":
...
/soc: node has a reg or ranges property, but no unit name
/soc/gpu: missing or empty reg/ranges property
/soc/firmware/gpio: missing or empty reg/ranges property
...
This happens because we pass dtc flags via KERNEL_EXTRA_ARGS directly on the
make command line, preventing scripts/Makefile.lib logic from appending flags
that silence dtc warnings (all assignments done from within a makefile, to a
variable specified on the command line, are ignored).
oe-core commit [1] introduced the dedicated KERNEL_DTC_FLAGS variable to pass
dtc flags via the environment. Use this variable to get rid of the do_compile
log noise.
The md5sums of the generated dtbs for raspberrypi3-64 and raspberrypi4-64 do
not change with this patch applied.

Before this patch, use of RPI_EXTRA_CONFIG += in a local.conf would overwrite
the needed 'arm_64bit=1' defined in the core recipes. The net result would be
a system that did not boot.
This patch fixes the assignment of 'arm_64bit=1' even if RPI_EXTRA_CONFIG
has been set elsewhere.

To allow other layers to easily provide a default kernel preference to
use with the Raspberry Pi MACHINEs, switch to use the ??= assignment
operator for setting the default kernel and the device tree value in
this layer.
This change is motivated by enabling Xen support in meta-virtualization
to use the raspberrypi4-64 MACHINE definition from this layer with the
Yocto Linux kernels.
